KDF is an alloy of copper and zinc that is used in most shower
filters and some drinking water filters. It removes free chlorine from
water by reversing the electrochemical process that originally produced
the chlorine. Chlorine is created by separating chloride ions from
sodium in a brine solution.
Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc
formulation that uses a basic chemical process known as redox
(oxidation/reduction) to remove chlorine, lead, mercury, iron, and
hydrogen sulfide from water supplies. The process also has a mild
anti-bacterial, algaecitic, and fungicitic, effect and may reduce the
accumulation of lime scale.
KDF process media is used in pre-treatment and primary treatment
applications to supplement or replace existing technologies in order to
extend system life and to reduce heavy metal contamination, chlorine and
hydrogen sulfide. It is often combined with other technologies to
achieve superior overall results. Because of its effectiveness at higher
water temperatures, it is often used on shower water filtration systems
to remove chlorine and other contaminants. The technology was developed
by KDF Fluid Treatment, Inc. in the mid 1980s and was patented in 1987.
KDF filter media meets EPA and Food and Drug Administration standards
for levels of zinc and copper in potable water, and is certified by NSF
International to its Standard 61 for drinking water.
Kinetic Degradation Fluxicon (KDF) water filters use the Redox
(oxidation/reduction) chemical process. Redox works by changing the
structure of the damaging contaminants. The structural change is brought
about by transferring electrons between two media and creating one
positive and one negative charge.
The KDF water filter contains two process media, one with negative
charge and the other positive. All chemicals contain atoms, these atoms
are also charged either positively or negatively. As the chemical passes
through the KDF water filter process positively charged atoms get
attracted to the negative charge in the filter and the same happens to
negatively charged atoms being attracted to the positive charge in the
filter. The transfer of electrons that happen during this process
changes the make up of possibly harmful chemicals.
KDF filtration does add trace amounts of copper and zinc to the
water. These small amounts of copper inhibit growth of viruses, algae,
fungi, and bacteria in the water. These trace amounts are well below the
daily required minimum of copper, so there's no way you'll get too much
copper in your diet. Assuming you're not going to drink an entire
KDF water filters are something that you should look into when
weighing your water purification options. This type of water filter is
steadily gaining popularity because it has been found to be an effective
water treatment option; it�s also affordable, has multiple applications
and has the capacity to eliminate a wide range of contaminants without
employing the use of harmful substances.
